Subject: [PATCH 9/9] arm64: fpsimd: Remove obsolete cond_yield macro
Date: Tue, 31 Mar 2026 17:05:48 -0700	[thread overview]
Message-ID: <20260401000548.133151-10-ebiggers@kernel.org> (raw)
In-Reply-To: <20260401000548.133151-1-ebiggers@kernel.org>

All invocations of the cond_yield macro have been removed, so remove the
macro definition as well.
